I have a 17 year old Camry that has crystallized coolant on the reservoir neck just like your photo shows liquid there. Coolant level is never low. Done it since we bought it new. Perhaps a Toyota oddity.
That container should not be under pressure yet the leak looks like a pressure leak. So sometimes the container DOES build pressure?? gets shaken while in transit, some of the coolant under pressure leaks past the cap which is not designed for pressure.
Replace the cap and discharge hose on the overflow container. Cheap fix. See if it works. The inside of a rubber hose can deteriorate, or cap might have debris in it or some defect - either can cause pressure to develop. Might also want to check out the radiator cap.
